Looking at the amount of torsion put into the shaft (I just ran some similar calcs yesterday for a 1/2" shaft ) that shouldn't be the problem, What I was reffering to was that the point of failure will probably depend on the pin (either the pin itself, or the shaft where it engages the pin).


With so much time on your hands, and since you already modelled it anyway, you my as well learn to use the stress analysis built into inventor to check your it. I've been using this all season on critical parts and it has never failed me (remember to build in a safety margin).
